Design and Construction Technology of Salt-marsh Plant Planting Project in the Intertidal Zone of the Yangtze River Estuary

在生物种青工程中,根据自然法则人工构建盐沼植被打造滩涂栖息生境基底,满足滩涂动植物生长所需的环境条件,有利于滩涂生态修复。同时,采用本土种青植物(如芦苇和海三棱藨草)优先占据滩地能够有效抵御外来入侵物种的扩散,扩大本土动植物生境,有利于维持生物多样性。文章通过研究影响植物空间分布的关键因素,论证了2022年度生物种青工程种青高程及平面布置,设计了相应的种植方案,可为同类型生态修复工程设计提供参考。

According to the natural law,the biological seeding project artificially constructs salt marsh vegetation to create the base of mudflat habitat,which meets the environmental conditions required by the growth of mudflat animals and plants,and is conducive to the ecological restoration of mudflat.At the same time,using native green plants(such as reeds and seagrass)to occupy the beachland preferentially can effectively resist the spread of invasive alien species,expand the habitat of native animals and plants,and help maintain biodiversity.By studying the key factors affecting the spatial distribution of plants,the article demonstrates the elevation and layout of the 2022 Salt-marsh plant project,and designs the corresponding planting plan.The engineering design can provide a reference for the design of similar ecological restoration projects.
